its not an excuse to u but it is excuse for them.
think of it as business prospective, not as subscriber prospective.
yeah, sure u want all sport available, but as an astro part, they need to buy that right to broadcast it.
sure they can broadcast it at astro supersport, but how long they will last? eventually some of sentanta subscriber will be mad at them and tell why they need to pay extra since they already broadcast it in supersport. that is when conflict will happen.

sure they suck your wallet to dry, but you cant blame them for everything
they are doing their business..
u also have the option to not subscribe to them

there are 3 option
1. if you have sport pack you can add the channel by ala carte that will be price at rm53
2. By subscribing sport focus pack which you can have 3 channel, Cricket, Sentanta and WWE will be price at rm37.10 (must have sport pack in your subscription to get that pack)
3. no sport pack, just ala carte at price at rm53.
